Back from the dead but this seems like a good place to ask

My truck's box (reman from Lares, '86 C10 unit) went nut & washer --> pitman --> grommet--> snap ring--> washer -->seal -->needle bearings.
The seal kit listed for this box is always PSK-1, which is a two-seal kit.
I looked up the part number for the single seal and it is listed as the "lower" seal (shorter of the two) in the PSK-1 kit.
There is no room under the snap ring for the second seal.
Anyone run into this, know what could be going on here? The seal I took out had under 150 miles on it and leaked like a sieve. I did use Dextron instead of PS fluid, which I won't do again, but I don't want to put the box back in the truck until I'm confident of the story.
